Kartikey Bhatnagar

I architect full-stack applications that don't fall apart at 3 AM. React, Node.js, real-time systems, and the occasional AI integration when it actually makes sense (not everything needs GPT-5). Currently building tools that developers actually want to use.

Movies

A curated watchlist of sci-fi and engineering stories, films that think about systems, problem-solving, and consequences the same way I do.

Gears

The desk setup, keyboard, editors, and everyday development tools I actually use tuned for speed, focus, and shipping without friction.

Music

The playlists that get me through long debugging sessions and late-night builds coding tracks and favorites I keep coming back to.
